The new app publishing format, the Android App Bundle, is a more efficient way to
build and release your app. The Android App Bundle lets you more easily deliver a great
experience in a smaller app size, allowing for the huge variety of Android
devices available today. It's easy to switch. You don’t need to refactor your code
to start benefiting from a smaller app.

Available in Android Studio 3.2 or later and the Unity 2018.3 beta release.

Manage releases more efficiently

With the Android App Bundle, you build one artifact that includes
all of your app's compiled code, resources, and native libraries for
your app. You no longer need to build, sign, upload, and manage
version codes for multiple APKs.

Benefit from a smaller app

Google Play’s Dynamic Delivery uses your Android App Bundle to
build and serve APKs that are optimized for each device configuration.
This results in a smaller app download for end-users by removing unused
code and resources needed for other devices.

Further reduce the size of your app by installing only the features that
the majority of your audience use. And then, with Dynamic Delivery,
users can download and install dynamic features when they’re needed.
Use Android Studio 3.2 to build apps with
dynamic features, and join the beta program to publish them on Google Play.
